The Department of Justice under President Joe Biden and 16 state attorneys general have brought an antitrust suit against Apple for allegedly illegally monopolizing the smartphone market.

The complaint, filed in the U.S. District Court for the District of New Jersey, accuses Apple of maintaining an illegal monopoly by “selectively imposing contractual restrictions on … developers” and undermining “apps, products, interoperability, and lower costs for consumers and developers,” according to the DOJ’s recent press release.
